A transcriptome-wide analysis in mice found that a protein-restricted (PR) diet during gestation resulted in differential gene expression in approximately 1% of the fetal genes analyzed (235/22,690). Specifically, increased expression was seen in genes involved in the p53 pathway, apoptosis , negative regulators of cell metabolism, and genes ...
Nutritional genomics, also known as nutrigenomics, is a science studying the relationship between human genome, human nutrition and health. People in the field work toward developing an understanding of how the whole body responds to a food via systems biology, as well as single gene/single food compound relationships.
Furthermore, nutrition can affect methylation as the process continues throughout an individual’s adult life. Because of this, nutritional epigeneticists have studied food as a form of molecular exposure. [1] DNA methylation is the addition of a methyl group on a cytosine ring of DNA. [15]
The human genome contains on the order of 20,000 genes which work in concert to produce roughly 1,000,000 distinct proteins. This is due to alternative splicing, and also because cells make important changes to proteins through posttranslational modification after they first construct them, so a given gene serves as the basis for many possible versions of a particular protein.

2'-O-methylation, m6A methylation, m1G methylation as well as m5C are most commonly methylation marks observed in different types of RNA. 6A is an enzyme that catalyzes chemical reaction as following: [9] S-adenosyl-L-methionine + DNA adenine S-adenosyl-L-homocysteine + DNA 6-methylaminopurine
DNA (cytosine-5)-methyltransferase 3A (DNMT3A) is an enzyme that catalyzes the transfer of methyl groups to specific CpG structures in DNA, a process called DNA methylation. The enzyme is encoded in humans by the DNMT3A gene. [5] [6] This enzyme is responsible for de novo DNA methylation. Such function is to be distinguished from maintenance ...
Creating genetically modified food is a multi-step process. The first step is to identify a useful gene from another organism that you would like to add. The gene can be taken from a cell [72] or artificially synthesised, [73] and then combined with other genetic elements, including a promoter and terminator region and a selectable marker. [74]
